Magnepan MG1.7 fuse question


I have placed an order for a pair of 1.7s. I want to upgrade the fuses but I don't know what spec is shown on the back place for the fuse. One person thought the spec was for a 4amp but I thought that seemed high. Could someone please let me know what the amp size it is. I assume it's a fast blow. Any help would be appreciated.

I remember that burned tweeters not covered and You make a good point to install the correct fuses.
Thanks
I've heard first hand how the HiFi Tuning Fuse improve the Magnepans, the best improvement one can make to the speakers for the least dollars. Its good to have the correct fuse value now, thanks.
Empirical Design Jumpers are new to me, really interesting, I'll have research this.

If you don't playback at very loud volumes that drive your amp to clipping you do not need any fuse at all!

I suggest brass or copper tubing cut to length in place of a fuse.

Fuses only degrade the sound IMO.
